Originally from Scotland, Dave Duncan lived all his adult life in Western Canada, having enjoyed a long career as a petroleum geologist before taking up writing. Since discovering that imaginary worlds were more satisfying than the real one, he published more than 60 novels, mostly in the fantasy genre, but also young adult, science fiction, and historical.

He wrote at times under the pseudonym Sarah B. Franklin (but only for literary purposes) and Ken Hood (which is short for "D'ye Ken Whodunit?")

His most successful works were fantasy series: The Seventh Sword, A Man of His Word and its sequel, A Handful of Men, and seven books about The King’s Blades. His books have been translated into 15 languages, and of late have been appearing in audiobook format as well.

He and Janet were married in 1959. He is survived by her, one son and two daughters, as well as four grandchildren.

He was both a founding and honorary lifetime member of SFCanada, and a member of the CSFFA Hall of Fame.
